zz claims. (ci. 5119a My invention relates to improvements in bufflng wheels, and the object of my invention is to provide a bulng wheel incorporating the use of pleated strips as some of the bufling layers, such strips being wound around the axis of the buil in substantially the same manner as shown in my United States Patent No. 1,927,862 with is to position some of the pleated rings with their inner face edges attached to the fabric discs intermediately of the radii of the fabric discs so that such pleated rings are only contained within the outer portion of the buff and thus build upthe buff in the outer portion thickness, and a further and also particular object of my invention is to secure the inner base edge portions of the pleated rings to the plain fabric discs by a plurality Aof substantially straight lines of stitching positioned in tangential relation to the centre of the ring, as shall be hereinafter explained.

My invention consists of a bufling wheel constructed and arranged all as hereinafter more particularly described and illustrated in the accompanying drawings in which:-

Figure 1 is a plan view of a bufiing wheel section constructed according to my invention, the outer plain fabric disc being shown unsewn and folded back.

Figure 2 is a schematic view showing the superimposed layers of pleated fabric forming part of a section.

Figure 3 is a perspective view of a fragmentary portion of pleated fabric from which the pleated rings are formed.

Figure 4 is a reduced plan view of a bung wheel section wherein the pleated rings are similarly positioned within the section.

Figure 5 is a side elevational view of the section shown in Figure 4.

Figure 6 is a similar view to Figure 4 showing a bumng Wheel section containing pleated rings positioned to provide a buil section of uniform thickness.

Figure '7 is a side elevational view of the section shown in Figure 6.

Figure 8 is a plan view of a buillng wheel wherein the illustrated section is made up of a plurality of at fabric strips sewn to a plain fabric disc.

' Figure 9 is a plan view of a piece of fabric from which the strips shown in Figure 8 are cut.

Figure 10 `is a plan view of a buing wheel showing one type of stitching which may be used for uniting the various sections making up the buff, and

Figure 11 is a perspective view of a larger type of buif which is shown partly broken away to disclose two forms of pleated rings which are incorporated therein.

Like characters of reference indicate Correspending parts in the different views in the drawings.

My bufng wheel as illustrated in Figures 1 and 2 comprises a qlurality of plain fabric discs I each having a central spindle-receiving orifice 2. A number of these plain discs carry pleated rings 3 which are formed from lengths of pleated material 4 as illustrated in Figure 3, the material being in pleated strip form and the pleats secured in4 place by a line of stitching 5 in the vicinity of one edge. In making the builing wheel, a pleated strip is laid upon a plain disc layer with its sewn edge innermost and h laid in a plurality of substantially straight lines positioned in tangential relation to the centre of the ring. The pleated ring is then sewn to the plain disc layer as with a line of sewing 6. As illustrated in Figure 1, the inner edge of the pleated ring is of hexagonal form, though, of course, the outline of any straight-sided figure can be followed. It will thus be seen that the pleated portions 1 extending from the straight base edges remain in substantially closed form and that the pleated portions 8 radiating from the corners 9 are distended from the base edge to the periphery.l When the pleated strips are rst sewn vin this position the outer edges are also of the same contour as their inner or base edges, but during the course of construction they are Cut around their outer edges to circular form.

By placing the pleated strips in hexagonal or other` straight-sided figure form, I have provided the corners 9 which are a greater distance from the centre of the wheel than the straight sides so that as the wheel becomes worn down in use the corners are first worn or cut away before the straight baseedges are reached, and in this way there is no possibility of the pleated strip being y torn from out ofthe buil as the buif is worn down to approach the lines of sewing securing the pleated layers to the plain discs. If the pleated layers were secured to the plain discs in circular form. the circular lines of stitching would be reached and severed as units as the buff was worn down, with the possibillity of the remainders of the circular rings being violently torn out of the buff during operation. With my present construction the wearing down of the bu gradually cuts across the lines of attachment sewing between the plain discs and the pleated rings whereby the rings are not cut entirely loose.

As the portions 8 of the pleats are distended, they, of course. do not contain the same thickness of fabric as do the non-distended pleated portions and if the bui section is built up so that the pleated rings are all in the same position as illustrated in Figures 4 and 5, a buff will be produced wherein certain portions i of the edge are thicker than other portions ii. This type of buff finds a use in cases where it is desired to obviate cutting marks on the article being buffed, as the cutting edges of the fabric are of undulated form and, therefore, will not make straight cutting marks.

In Figures 6 and '7, I show a builng wheel l2 wherein the pleated rings are in staggered relation to one another, that is, the corners 9 of the ring overlap the straight sides of another ring. By this construction the buing wheel approaches a uniform thickness.

In Figure 8 I show an alternative construction wherein a section of the bufiing wheel is made up of a plurality of fabric strips i3 which are cut from a length of fabric M as illustrated in Figure 9. These fabric strips I3 are of trapezoidal form and their end edges l5 are so cut that when the strips are laid around a centre, as illustrated in Figure 8, they form a hexagon. The strips are laid upon a plain fabric disc I6 and are sewn thereto by a hexagonal line of stitching il. After the buff section is built up in this form it is circularly cut as around the dotted line i8.

Figure 11 shows my bufling wheel incorporating two types of pleated fabric rings, that is, a ring I9 having its base edge 20 of circular form as shown in my United States Patent No. 1,927,862 and also a pleated ring 2l of hexagonal form and attached to a plain fabric disc 22 by lines ofv stitching 23. 'I'he outer ring 2| is provided to build up the outer thickness of the buff, as due to the long pleats extending from the centre of the buff to the periphery ,in the section I9, such pleats are considerably distended and reduce the thickness of the buff, it being understood that such a bumng wheel is generally made up of a plurality of layers I9, plain discs 22 and outer pleated rings 2|.

One of the particular features of my buff construction is to form the core or centre portions 24 of the buis of a cheap fabric, such as burlap,

material and join the ends by a row of stitchingv 26. Upon reference to Figures 1and 11 of the drawings. it will be seen that I space the pleated rings away from the fabric cores 24 so that an air pocket is provided, and this air pocket 'in conjunction with the air spaces or pockets formed between the pleated rings and the plain fabric discs tends to keep the buffs comparatively cool in operation.

While I have specified my rings as being pleated, it is to be understood that the term pleated is considered to be synonymous with "puckered" or 5 gathered. In the drawings I have shown what are called bun` sections" and it will be understood that a number of these sections are tted side by side upon a spindle to form what is known as a bufling wheel". l
